The 5ACE_4 Series from Gaptec Electronic are Isolated Single-Output AC-DC Converters that convert an AC input voltage of 85 - 264 V to a DC output voltage of 3.3 - 24 V. They also accept a DC input voltage of 120 - 370 V. These converters deliver an output power of 5 W and have an efficiency of up to 81%. They offer a regulated output with low output ripple and noise while providing maximum isolation of up to 4000 V (AC), making them suitable for highly efficient and reliable operations. They incorporate short circuit protection, output over-voltage protection, and over-current protection circuitries to prevent over-load-related damages, and also deliver CISPR 32/EN55032 Class B-qualified EMC performance. These RoHS Compliant converters are available in a PCB-mount package that measures 37 x 24.5 x 18 mm and are ideal for industrial, electricity, instruments, telecommunication, and civil applications.
